GAP Manual: 7 Groups

The centralizer of an element x in G is defined as the set C of elements c of G such that c and x commute. gap> s4 := Group( (1,2,3,4), (1,2) ); Group( (1,2,3,4), (1,2) ) gap> v4 := Centralizer( s4, (1,2) ); Subgroup( Group( (1,2,3,4), (1,2) ), [ (3,4), (1,2) ] )

For other values of t, we can see that G/Z(G) is isomorphic to a subgroup of the group A × ,S4, × ,S4, , where A is an abelian 2-group. But |G : Z(G)| = 16 and so #Cent(G/Z(G)) = 1, 4 or 16, a contradiction.

It is interesting and somewhat unusual that Theorem 1.3 involves only a hypothesis on the exponent of CG (α) rather than the ,centralizer, of the subgroup of order three as in Theorem 1.2. It is well-known that the Sylow 2-subgroup ,of S4, is isomorphic with D8 , the dihedral group of order 8.

This and more was later confirmed by two of his students B. Lou and S.V. Keny, even for fields of "bad" characteristic. For X ∈ g, the Lie algebra of G, there are actually two relevant centralizers: the subgroup GX of G fixing X under the adjoint representation Ad, and the subalgebra gX of g fixing X under ad.
